check / check (push) Waiting to run
A backup uploads its blobs before the manifest that lists them, and the process lock covers one user on one machine, so a prune from another host or user sharing the destination deleted a running backup's blobs. Prune now deletes an unreferenced blob only once its listed time is older than the new config key prune_grace_period (default 24h; a negative value is refused). A newer blob, or one listed with no time, is kept and counted (blobs_too_new). A backup uploads a blob already on the destination again instead of skipping it, so it gets a fresh time. The rclone backend takes each object's time from the listing (use_server_modtime). Cost: after database delete, the next backup uploads all its data again. Side effect: a rebuilt blob replaces the stored copy; if compression_level or the recipients changed since, older snapshots listing it fail verify. Model: opus-5-5
